    Abstract: Conventional electrochromic devices frequently suffer from poor reliability and poor performance. Improvements are made using entirely solid and inorganic materials. Electrochromic devices are fabricated by forming an ion conducting electronically insulating interfacial region that serves as an IC layer. In some methods, the interfacial region is formed after formation of an electrochromic and a counter electrode layer. The interfacial region contains an ion conducting electronically insulating material along with components of the electrochromic and/or the counter electrode layer. Materials and microstructure of the electrochromic devices provide improvements in performance and reliability over conventional devices.

The addition of very small amounts of alloying element to pure aluminum and aluminum alloy target improves the uniformity of the deposited wiring films through affecting the target's recrystallization process. The range of alloying element content is 0.01 to 100 ppm by weight, which is sufficient to prevent dynamic recrystallization of pure aluminum and aluminum alloys, such as 30 ppm Si alloy. The addition of small amount of alloying elements increases the thermal stability and electromigration resistance of pure aluminum and aluminum alloys thin films while sustaining their low electrical resistivity and good etchability.
